No non-breaking space filter is a very simple filter module that deletes all non-breaking spaces ( ) and does nothing else. All non-breaking space HTML entities are replaced by blank space characters. Multiple contiguous space characters are replaced by a single blank space character. Of course the non-breaking space HTML entity has its right to exist. But serveral consecutive non-breaking space entities in a continuous text break all typographical rules. But when texts are copied from text processors like Microsoft Office Word or Libreoffice Writer into the Drupal WYSIWIG editors, it can happen, what not should happen ...
